Keratinization is part of the physical barrier formation (cornification), in which the keratinocytes produce more and more keratin and undergo terminal differentiation. The fully cornified keratinocytes that form the outermost layer are constantly shed off and replaced by new cells.
Microscopy of keratin filaments inside cells. Keratin (/ ˈ k ɛr ə t ɪ n / [1] [2]) is one of a family of structural fibrous proteins also known as scleroproteins.It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin in vertebrates.
The most common way is to display a family tree on Wikipedia is as an ahnentafel by Template: Ahnentafel. However, there are other options. This page originated in examples taken from a discussion on the Village pump in March/April 2005 (see Talk page). It has since been updated to use later created templates.
Keratinization begins in the stratum spinosum, [5] although the actual keratinocytes begin in the stratum basale. [4] They have large pale-staining nuclei as they are active in synthesizing fibrillar proteins, known as cytokeratin, which build up within the cells aggregating together forming tonofibrils. The tonofibrils go on to form the ...
Parakeratosis is a mode of keratinization characterized by the retention of nuclei in the stratum corneum. [1] In mucous membranes , parakeratosis is normal. [ 2 ] In the skin, this process leads to the abnormal replacement of annular squames with nucleated cells.

Because of the differences between mucous membranes and the skin (e.g., keratinizing mucosa does not have a stratum lucidum and non keratinizing mucosa does not have this layer or normally a stratum corneum or a stratum granulosum), sometimes specialized texts give slightly different definitions of hyperkeratosis in the context of mucosae.
